Great post - thank you!

I've got a Wordpress plugin which adds a button to the TinyMCE WYSIWYG editor.

In WordPress 3.9-Alpha the button no longer displays and it prevents the rest of the WYSIWYG buttons from displaying.

Does anyone have some advice about where might be the best place to start looking in the plugins code to make it play nicely with the new version of TinyMCE?

I greatly appreciate it.

Cheers :)
